I do believe it's an issue with the 510 SSD and Intel Rapid Storage Technology. I have 3 Intel 510 SSD's on 3 units and they all have this issue. When I was using 10.0, the SMART data were updating normally. After I updated to 10.5, 10.8,11.0, and 11.1, the data logs stopped updating the values. I hope this will be fixed in future versions of Intel Rapid Storage Technology.

Sorry but I don't have a solution. Just wanted to say that I noticed the same thing. My 510's are over a year old now and I was worried that the Media Wearout Indicator value in the Intel SSD Toolbax would never be accurate if the Host Writes kept resetting after 4TB.

I lost count of the number of times that I hit the 4TB limit and then reset. But I just now checked the toolbox and I finally see a change in the E9 media wearout indicator. It now shows 99% instead of the 100% under Normalized heading. So maybe that part is still functioning.

I would not be watching for a firmware update for the 510 to fix that SMART data, as the chances it will be are virtually zero. While the 510 is not yet considered "End of Life" in the Intel ARK data listing, it has not been available for retail purchase for a while now. I doubt it has been manufactured since early 2012 at the latest. Intel rarely issues firmware updates, and only for important issues, which is not the case with that SMART data value. It's possible that the SMART values displayed in the Toolbox are not the only attributes being logged.

I just learned that quite a few Intel SSDs are being discontinued, including the 520, 525, 313, and 320. If those newer models are being discontinued, what are the chances the 510 will have a firmware update for that one SMART value, if it even is a true problem.

My thought exactly (there hasn't been public firmware update to 510 model ever, unlike for instance X-25M or 320 which seen several updates already), I just thought you guys should know it is known issue.
